I've been using it for a few weeks now. I have a MacBook Pro 2018 with Sonoma 14.1.1 . It keeps crashing every 4 or 5 exercises in each chapter. It's extremely disappointing. If Apple wants people to learn its new programming language and tools(Xcode) they should make at least products that work. Xcode is one of the worst IDEs out there. Not to mention that it too crashes often despite its constant 4GB and up updates. It's embarrassing.
